Condensation

The alumina refining industry is one of a number of global industries that produce process waters containing mercury. The research program detailed in this dissertation focuses on processes for removing mercury from Bayer digestion condensate streams. Bayer refinery digestion condensate is chemically unique because it exhibits high pH and is chemically reducing, thermodynamically favouring the presence of elemental mercury.

Purpose: Developing mean-field theory for a 2D two-band model including electron – phonon interaction and the extended Falicov-Kimball model involving electron/hole – phonon interaction. Studying the properties of electronic systems in EI state through investigating the above models. Then, we compare the nature of each condensation state on both sides of the BCS – BEC crossover or the competition with the CDW state.

Trạng thái ngưng tụ Bose - Einstein được tạo ra đầu tiên trên thế giới (BEC - Bose - Einstein condensate) từ những nguyên tử lạnh năm 1995. Điều này có ý nghĩa lớn là tạo nên một dạng vật chất mới trong đó các hạt bị giam chung trong trạng thái ở năng lượng thấp nhất, đã mở ra nhiều triển vọng nghiên cứu trong Vật lý. Đây là lĩnh vực đã và đang thu hút được sự quan tâm của nhiều nhà Vật lý trên thế giới.

The Arabidopsis FAE1 b-ketoacyl-CoA synthase (FAE1 KCS) catalyzes the condensation of malonyl-CoA with longchain acyl-CoAs. Sequence analysis of FAE1 KCS predicted that this condensing enzyme is anchored to a membrane by two adjacent N-terminal membrane-spanning domains. In order to characterize the FAE1 KCS and analyze its mechanism, FAE1 KCS and its mutants were engineered with a His6-tag at their N-terminus, and expressed in Saccharomyces cerevisiae. The membrane-bound enzyme was then solubilized and purified to near homogeneity on a metal affinity column.

In this review, we summarize recent progress in studying three main classes of prenyltransferases: (a) isoprenyl pyrophosphate synthases (IPPSs), which catalyze chain elongation of allylic pyrophosphate substrates via consecutive condensation reactions with isopentenyl pyrophosphate (IPP) to generate linear polymers with defined chain lengths; (b) protein prenyltransferases, which catalyze the transfer of an isoprenyl pyrophosphate (e.g. farnesyl pyrophosphate) to a protein or a peptide; (c) prenyltransferases, which catalyze the cyclization of isoprenyl pyrophosphates.

4-Coumarate:CoA ligase (4CL) is involved in the formation of coenzyme A thioesters of hydroxycinnamic acids that are central substrates for subsequent condensation, reduction, and transfer reactions in the biosynthesis of plant phenylpropanoids. Previous studies of 4CL appear to suggest that many isoenzymes are functionally equivalent in supplying substrates to various subsequent branches of phenylpropanoid biosyntheses. In contrast, divergent members of a 4CL gene family were identified in soybean (Glycine max L.).
